IMPROVEMENT IN EEVOLVINGLGYLINDER ENGINE.

To ALI. WIIoM'IT MAY ooNcEnN:

Be tknown that we, QnALMEns SCOTT and WILLIAM H. MonToN, of Hamilton, in Ythecounty of Butler, and State of Ohio, have invented a new and-improved Revolving-Cylinder Steam Engine; Aand we do hereby declare that the following is a full, clear, and exact, description thereof, which will enable-others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming 4part of this Vspecification'.

This invention relates to a new and improved application of' the steam engine for the purpose of'v producing rotary motion; and the invention consists in suspending the cylinderin tru'nnions and revolving it with the lyf wheel in the manner hereinafter described. I

Figure 1 is a side elevation of' thel engine, showing the {1y-'wheel and the frame by which the cylinder is supported.

Figure 2 is a top or plan view. p

Figure 3 is a central section of the cylinder detached, thesection-'being through the line .t :c ot' iig. 1.

Similar letters of reference indicate like parts.

A ,is the cylinder, which revolves on two trunnions. B represents a platform, which supports three stands which are'marked C. D is the horizontal engine-shaft, which revolves in boxeson the top of the stands. This shaft is a tube, and passing directlythrough it is a stationary rod or bar, the inner end of which has an arm attached to it nlarked a, and one of .the trunnions'lof the cylinder is supported by this arm.V The -distance 'of the centre of the trunnion tothe centre of the shaft D is the crank l'everageof the engine. The other trunnion is supported by the stand marked C. .The steani-cylinder is constructed like the ordinary reciprocating enginecylinder, the piston-rod of which is connected with the rim of the ily-wheel E by a wrist-pin marked f. The steam-ports o f the cylinder are formed in the outer trunnion, and they are so arranged that the piston takes steam at each end of the cylinder alternatelyv as the cylinder revolves. l

Figure Ashows the position of theports c ande in or through the trunnion.

Figure 5 shows the reversing-valve and lever y. Y

Fig. 3 represents the exhaust pipe when the cylinder takes steam, as represented by the arrows. When the motion of the engine is reversed bythe reversing-valve, 5(the-lever of which is seen at g, g. 3,) `this exhaust-port would be closed, and the'steam would be exhausted from the port c through the pipe e, seen in fig. 1. The pOLt-trunnion is recessed, and the valve is kept to the face of the trunnion by neet-screw in the centre. The valve andvend of the trunn'ion'are covered with a boxing having a at place on its inside for' the valve to s ct on, and the valve is kept from revolving by a-'set-screw in -a slot, so that the centre set-screw can set it up to the face of the trunnionwhen necessary. As the cylinder in its revolution comes on a horizontal line with the centre of the ily-wheel 4shaft D, the openings in thetrunnion will come opposite to the openings in the valve in' the manner of a slide-valve and admit thesteam. By`the arrangement shown of two exhaust pipes and cocks or valves in eachV steam pipe, it will be seenI that by-shutting and opening the properones we-czm reverse the mot-ion of the engine when necessary.

What we claim as new, and desire to secureby Letters Patent, 1s`

The arrangement of the hollow-revolving shaft D, having thestationary bar passing through it, 'to which is secured the arm a, cylinder 4Lidy-.wheel E, and lstand, substantially as described, for the purpose specified.
